if a confidence interval is given from 8.50 to 10.25 and the mean is known to be 9.375 what is the margin of error
Homework Answers
Margin of error is given by=9.375-8.5=0.875, which is also equal to 10.25-9.375. Basically , for a both side equal confidence interval, maargin of error is given by Upper Confidence Limit- Mean or Mean-Lower Confidence Limit

Confidence Interval Given. Assume I created a 95% confidence interval for the mean hours studied for a test based on a random sample of 64 students. The lower bound of this interval was 4 and the upper bound was 14. Assume that when I created this interval I knew the population standard deviation. Using this information, (a) Calculate the width of the interval. (b) Calculate the margin of error for the interval. (c) Calculate the center of the interval. (d)...
